Swift3 重复通知Swift 3

我有只适用于一个时间项目的通知。我需要出示我的通知：晚上10:00和10:30。我怎么能做到？请告诉我

我的代码：

NotificationManager.swift：

import UIKit
import UserNotifications

class NotificationManager
{
static let shared = NotificationManager()
let center = UNUserNotificationCenter.current()

func registerNotifications()
{
    center.requestAuthorization(options: [.sound,.alert], completionHandler: {( granted, error) in })
}

func addNotificationWithCalendarTrigger(hour: Int, minute: Int)
{
    let content = UNMutableNotificationContent()
    content.title = "Hi"
    content.body = "It,s new notification!"
    content.sound = UNNotificationSound.default()

    var components = DateComponents()

    components.hour = hour
    components.minute = minute

    let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
    let request = UNNotificationRequest(identifier: "calendar", content: content, trigger: trigger)

    center.add(request) { (error) in
        //handle error
    }
}
}

ViewController.swift

import UIKit

class ViewController: UIViewController
{
override func viewDidLoad()
{
    super.viewDidLoad()
    timeForNotifications()
}

override func didReceiveMemoryWarning()
{
    super.didReceiveMemoryWarning()
}

func timeForNotifications()
{        
    NotificationManager.shared.addNotificationWithCalendarTrigger(hour: 22, minute: 00)
}

}

可能有点晚了，但我想这就是你要找的。您可以使用以下代码将通知设置为在10:00显示：

var components = DateComponents()

components.hour = 22
components.minute = 00

let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
let request = UNNotificationRequest(identifier: "calendar", content: content, trigger: trigger)

我经常做的是用日期替换组件，但我认为您的选项也适用

var date = DateComponents()
date.hour = 22
date.minute = 00
let trigger = UNCalendarNotificationTrigger(dateMatching: date, repeats: true)

希望这对你有帮助

您从未设置过委托中心。delegate=self也不要忘记为类设置UnuseNotificationCenterDelegate
